Summary:
In this paper, we propose a real-time and less-computation authentication methods for broadcast communication in V2X. The proposed method solves the key sharing and non-repudiation problems by using an existing broadcast authentication protocol, TESLA, by defining a new mediator function between the sender and receiver and deploying it in the Communication Base Station. The proposed methods are compared with existing technology and shown their superiority.
